mold clamping Limiet-Fs.

It is particularly :nlapteil for employ-- nient in connection with concret-e molfls in which tiefrode having adjustable rolizirs thereon :ire employe-l to hohl the Clamping l lizirs tightly ngxiwt the. side niemhers of the mold.

The plates 11. und 12 and halls 15 form n thrust hall bearing of the ordinary type. The tubular member 6 is proi'ided with a longitudinal Slot 16 in which is invoted5 on n trnnsveree pin 1T, :i lever 18, having n cem 'time 1S). nhieh, is adapted to relensnhly, loekingly engage a, tiefrofl 3 when tho inemler li is mounted. thereon, as shown in the drawings.

in the operation ol' my invention. the Side 7 members l. clamping harz-1 i2, tie-rods Il, :ind damping collare l, are nfsemhleil in their operative poSitfione. Shown in Fig. 3, the set Screw in one elfimping oollnr on euch tie-rod being tightened. while the set eerew et' the other coller is left untipghteneil so ne to permit the tiwrofl being .lrmvn through the clamping collar, :is hereinafter (leeerihed. The meml rs 6 sind 9 being inA screw threaded eonneciion with euch other, nre slipped on to one of :lv tie-rods to n position in which the hezorng plate 12 is against the. clamping coll n: -l in which the Set- Serew has not been tiglitenrn, as shown in Fig, l. The cam lever 13 if; then swung to the left, as viewed in 1` therel'iy onnsin the cam ffice 19 to loekingly engage the inlyieent tie-rod 3. The tubular member or nut 9 is then turned in 2r direction such that the bearing plate 12 will force the ad jacent collar 4 and adjacent clamping bnr' i2 toward the opposite clamping bur und thereby clamping the side members 1 tightly together. The set screw 5 of the collar which has been adjusted is then tight- 95 eued againsst the tie-rod adjacent thereto. The cam lever 1.8 may now be swung to the right, as viewed in Fig. l, thereby releasing the members 6 and 9, which may he withdrawn from the tie-rod on which they are 100 mounted and placed consecutively on the other tie-rods of the mold for el'eoting the function hereinbefore deeorihed. By reir son of the thremleil connection between the members 6 und 9, the tightening device is 105 :nlfxneil for longitudinal expansion nf! efmtruetion` for the purpose of messing? against und for being rei-:iwi l.from the :u'liueent collar fl. l

I lo not limit my invention to the Stine itil ture described and Shown, as modifications, within the scope of the appended, claims, may be made without departing from the spirit of my invention.

Having thus described my invention, what I claim and desire to secure by Lettere Patent, is

i. ln a mold clamping device, a clamping collar. a tiered extending therethrough, re leasable means 'for lacking the collar to said rod, two tubular members mounted. on said. rod and having Screw threaded connection with each other and rotatable one relative to the other, a thrust ball bearingcarried by one of the tubular members and adapted to bear against and movable longitudinally on said rod, with the member which carries it7 independently of said collar, and means for releasanly lurking ihe other tubular member to l a nmld cflzunping device, a clamping 0d extending tlwi'etlii'ougli, relic-'usable n ne for locking the collar to said rod, two iunular menibf:n=,detaeliably mountn and ha Screw threaded e f, one tubular `I iw to the other,

li rolluik iii a tiiruet i bearing carried, by the rotary menibcr adapted te bear agninet and 3e movable "ufliiinily on nid red with the member i a i. imichel{lenily of other tubular uiember for releasable locking said member to said rod.

3. In a mold clamping device,'a,.tierod, two clamping collars mounted on said rod, each collar having means for being secured tightly'to said rod, one of the collars being longitudinally adjustable on said rod, and a tightening device adapted for longitudinal expansion and contraction and for longitudinal adjustment; on and having means for being: releasably locked to said rod, and

adapted to engage and longitudinally move and to be detached from said adjustable clam ing collar.

4. iin a mold clamping device, a tie-rod, a clamping cellar longifitudinally adjustable on said rod and having means for being releas' ably locked thereto, and a tightening device adapted for longitudinal expansion and contraction, and longitudinall adjustable on said rod independently o collar and adapted for longitudinally movingeaid collar, and provided with means for being; releueably locked to said rod.

in testimony whereof l have signed my naine lo thie` epeciication in presence of two subscribing witnesses.
